BOAT.

Application filed March 10, 1914. Serial No. 823,728.

To all whom it may concern:

Be it known that I, FRANCESCO MONTI- GLIO, a citizen of Italy, residingat Glastonbury, in the county of Hartford and State of Connecticut, haveinvented'new and useful Improvements in Boats, of which the following isa specification.

This invention relates to boats and particularly the propellingmechanism therefor, the object of the invention being to provide simplemechanism for actuating a screwpropeller at the stem of the boat, thesaid mechanism serving to apply continuous power to the propeller shaftand the initial element of the propelling mechanism being adapted to bedriven either by a pedal crank shaft or by any suitable motor.

A further object of the invention is to combine with such initialdriving element, and an operators seat arranged adjacent thereto, asteering rudder of novel construction arranged in the bow of the boatand operable by a hand controlled element also arranged adjacent to theoperators seat.

With the above and other objects in view, the invention consists in thenovel construction, combination and arrangement of parts, as will behereinafter more fully described, illustrated and claimed.

In the accompanying drawings :Figure 1 is a vertical longitudinalsection through a boat, showing the same equipped with the driving andsteering mechanism of this invention. Fig. 2 is a horizontal sectionthrough the same taken above the propelling mechanism. Fig. 3 is adetail horizontal section through the stern of the boat taken about inline with the propeller shaft which I is shown in elevation. Fig. 4 is adetail horizontal section through the bow of the boat showing therudder. Fig. 5 is a vertical cross section through the boat taken aboutmidships.

The boat which is generally designated at A may be of any desired sizeand general construction and is provided with the usual propeller 2 atthe stern thereof, the same being mounted on a propeller shaft 3extending through a shaft hole in the stern of the boat and beingprovided upon its inner end and within the boat with a bevel gear pinion4 the purpose of which will appear.

Arranged in front of the forward extremity of the propeller shaft andperpendicular to said propeller shaft is a countershaft 5 on which aremounted two bevel gear Specification of Letters Patent.

wheels 6 which rotate in opposite directions and both. of which meshwith the pinion 4 at opposite sides of the latter. outer sides the bevelgear wheels 6 are pro vided with ratchet faces or teeth 7 disposedinreverse directions as shown in the drawings, said ratchet faces beingengaged by pawls 8 arranged at opposite sides of the wheels 6 and beingslidable on a transverse pin 9 on a pawl actuating lever 10 which has,

its rear end j ournaled and fulcrumed on the .countershaft 5, such leverbeing adapted to move in a substantially vertical plane. A contractilespring 9 connects the pawls 8 and holds them in engagement with theratchet faces 7. It will be observed that as the lever 10 movesdownwardly, one of the pawls will engage with one of the gear wheels 6to revolve said wheel in one direction and when the lever moves in anupward direction, the other pawl carried thereby engages the ratchetteeth of the other bevel gear wheel-6 thereby rotating the last namedwheel in the opposite direction to the first named wheel. Continuousrotary motion is imparted in this way to the bevel gear pinion 4 andtherefore the propeller shaft and propeller.

At its forward end the lever 10 has pivotally connected thereto a pitman11 which is pivotally attached at its opposite end at the point 12 to arotary spur gear wheel 13. This wheel 13 is mounted on a shorttransverse shaft 14 and meshes with and is driven by another spur gearwheel 15 fast on a crank shaft 16 shown as provided with suitable cranksand pedals 17 adapting it to be propelled by the foot power of theoperator who occupies a seat 18 adjacent to said crank shaft. It will ofcourse be understood at this point that the crank shaft 16 may be drivenby any suitable motive power.

A section 19 of the bow of the vessel is utilized as a rudder, saidsection being normally flush seated in a recess 20 of corresponding sizeand shape in the bow of the boat. The said wedge-shaped rudder or boatsection 19 is fast on the lower end of a rudderpost 21 which is providedwith a pinion 22 fast thereon and meshing with a sector 23 mounted on asteering shaft 24 shown in the preferred embodiment of this invention asprovided with a hand controlled or steering wheel 25. This wheel is'arranged in convenient reach of the operator On their 7 while sittingin the seat 18 where he is also enabled to operate the propellingmechanism by means of his feet, and places the entire control of thepropelling and steering mechanism within easy reach of the operator.

26 designates a hood or housing which fits over the lever 10 and thepitman 11 and also forms a support for the seat 18 above reand meshingwith said pinion and provided on their outer sides with ratchet faces, afootpropelled crank shaft adjacent to the bow of the boat hull, a crankwheel geared to and rotated by said crank shaft, a transmission leverjournaled at its rear extremity on said countershaft between said bevelgears, a pin carried by said lever, pawls slidable on said pin at rightangles to said lever at opposite sides of the latter and cooperatingwiththe ratchet faces of said bevel gears, a contractile spring connectingsaid pawls,

and a pitman connecting the forward end. of

said transmission lever with the crank pin of said crank wheel.

In testimony whereof I affix my signature in presence of two witnesses.

FRANCESCO MONTIGLIO.
